Key legal question
Whether S. had established civil domicile in X. after entering the care home, making Zurich/X. competent for supplementary benefits.
Extracted holding
Yes. The voluntary, indefinite stay in the home, combined with the shift of life's center there, established a new domicile in X.
Extracted reasoning
Art. 23 and 26 ZGB allow a new domicile where a capable adult voluntarily chooses an indefinite institutional stay and the objective circumstances show the center of life has moved there. Registration or deposited papers are irrelevant.
